Google Cloud Go处理程序没有路由器Gorilla Mux？

问题描述

我在这里看到他们没有指定使用任何路由器...：

在Google Cloud与Golang一起使用时，它表示指定 app.yaml 中的每个处理程序。这是否意味着我们不应该使用第三方路由器来获得更好的性能？我想为路由器提供Gorilla Mux ...如果我为Google App Engine Golang应用程序使用其他路由器，它将如何工作？

请让我知道。感谢！

解决方案

您可以使用App Engine的Gorilla Mux。方法如下：

在。注册Gorilla路由器与DefaultServeMux来处理所有路径：

pre $ func init（）{
r：= mux.NewRouter （）
r.HandleFunc（/，homeHandler）

//路径/匹配与其他路径不匹配的所有内容。
http.Handle（/，r）
}

https://cloud.google.com/appengine/docs/go/users/

I see here that they do not specify to use any router...: https://cloud.google.com/appengine/docs/go/config/appconfig

In Google Cloud when used with Golang, it says to specify every handler in app.yaml. Does this mean we are not supposed to use 3rd party router for better performance? I would like to Gorilla Mux for router... How would it work if I use other routers for Google App Engine Golang App?

Please let me know. Thanks!

解决方案

You can use Gorilla Mux with App Engine. Here's how:

At the end of the handlers section of app.yaml, add a script handler that routes all paths to the Go application:

application: myapp
version: 1
runtime: go
api_version: go1

handlers:

- url: /(.*\.(gif|png|jpg))$
  static_files: static/\1
  upload: static/.*\.(gif|png|jpg)$

- url: /.*
  script: _go_app

The _go_app script is the Go program compiled by App Engine. The pattern /.* matches all paths.

The main function generated by App Engine dispatches all requests to the DefaultServeMux.

In an init() function, create and configure a Gorilla Router. Register the Gorilla router with the DefaultServeMux to handle all paths:

func init() {
    r := mux.NewRouter()
    r.HandleFunc("/", homeHandler)

    // The path "/" matches everything not matched by some other path.
    http.Handle("/", r)
}
